A dog barking at empty air has many reasons: sensing danger, finding insects, getting attention, or releasing emotion. Their smell and hearing are acute, detecting faint scents and inaudible sounds.
For example, when a dog senses earthquake waves, it often barks at the air to warn the owner. It may also bark to drive away small flying insects.
